To all whom t may concern:

Be it known that we, IVALTER S. TOWER, a citizen of the United States,and a resident of Wallace, in the county of Shoshone and State of Idahoand PETER D. CAMPH'ms, 'a citizen of the 'United States, and a residentof Wallace, in the county of Shoshone and State of Idaho, have inventedcertain newv movable within a tank containing water maintained at alevelfabovethe ore level.

The invention isfully described in thefol- .lowing specification, Vofwhichr the accom- -panying Ydrawings forma part, in which the separateparts kare ldesignated by the samer-reference characters' in each* ofthe views, vand in which f Figure v1 is-a sidek elevation of theinvention, partly in sectionon the line lfl of l Fig. 2; Fig. 2 is aplan view,thereof;Fig. 3

is a section taken on the'line 3 3 of Fig. 1; Fig. 4 is an enlargedsectional view of a detail, taken on theline 4-4 of Fig. 5; and Fig. l5is a similar view taken onthe line 5 5 of Fig.` 4; v

In the drawings forming ka .part vof this application we have shown atank 6, adapted to contain water, provided with transverse plates 7, andhaving` four brackets 8, two of 'which are-mountedupon each oftwosupporting plates 9 aboveand adjacent'theends of theV tank; pivotblocksy 10 are supported vat thetops of said brackets and servingrassupports for' springs 11 having, each.a `washer 12 at the top thereof tocarry a rod V13 vertically movablein thecorresponding pivot block and inpivotal connection with -ashaft 14 pivoted to brackets 15, beneath eachof the plates 9, secured to abasket 16 Specification of Letters Patent.

having rthe openl bottom .thereof covered Yby a screen 17, as clearlyshown in Figs. 1 and 13, and it willbe seenthat the springs 11 supportthe basket 16 but in such manner as to permit vertical movement thereof,whereas the pivot blocks 10v permit horizontal movement thereof. j I rf.

The'loasket` 16,is provided,above the screen 17, with a plurality of jtransverse plates 18 and withinclined.plates .19, of somewhatfgreaterlieight, than the plates 1 8,

kleading to corresponding cups 20 having an opening'inrthelowerportionthereof between the innerends of each pair of plates A19, asshown at 21,l Figs. 1 and 4, a gate 22 being vertically adjustableoneachcup to controlv lthe corresponding opening 21and` held in.position ,by means of .a spring 23 and bolt 24, tensionally, and eachcup is also provided with a transverse plate 25 provided with an opening26 rintermediate the height thereof controlled by agate 27 havingtwoopenings 28 and29-.therein and tensionally held by; means of a yspring8O and bolt 31,

.and it will be seen-thatfthel height of the opening, through thepartition so formed ,fp-

maybe regulated, from the screenf17, as may valso the size-of theopening.v Y

The screen 17 is held in placevby means o fa'plurality of longitudinallyarranged beams 32in turn held by brackets 33, Fig. 3,

l'secured'tovtransversevbeams 34 secured to theV lower side of the,`sidemembersof the lbasket and the basket' is falso fprovided with 'atransverse,'centrally1 arranged, plate 35 .secured tothe tops of thesidemembers, Fig.

3, by means ofbolts 3K6, bolts being also ypro.- videdforholding'bearings 37v for a stubshaft 38,Figs. land. j 1 M AvIounteduponvthe side membersv of the soA tank" 6 are two frame members 39 jserving as bearings fora. shaft 140 extending across v thetankandprovided with a fly-wheel 41 at onevend, andk two pulleys 42 and 43,one of other end, and said shaft also carries an eccentric diskk 44,centrally thereof, having a band 45 thereon from which depends a*Vpitman 46 providedy with teeth 47V and connected with the stub-shaft 38,and it will be seen that rotation of the power shaft 40 l l which istight and the other loose, at the Y classes or character.

moves the basket 16 up and down, this being' 'permitted because of thecoil springs 11.

tion by means of bolts 50, Fig. 1, and said block carries a stub-shaft51, Fig. 3', upon which is mounted a yoke-'shaped link 52 and the otherends of which are mounted upon a shaft 53 carried by two oppositelydisposed rock-bars 5i pivoted to the frame members 39 at 55 and providedwith segmental arms 56 having, each, a slot. 57 therein, and throughwhich passes a bolt 58 whereby said rock-bars maybe lockedin adjustedposition to a portion 58a ofthe said frame members. i It will b'e seentha-t,if the block 48 be vertically adjusted on the pitman 46, the hori-'zontal throw fof the pitm-an is changed accordingly, this also beingtrue if the rockarms are vertically adjusted, and doubly so if each beoppositely adjusted, although they may be adjusted to insure anelliptical path of movement vof the block 48 the major aXis of which isperpendicular to the tank, but we desire to so adjust these parts as toinsure an v inclined position of the major axis, whereby an inclined,elliptical, path vof movement of the basket 16 results, preferably atsuch inclination asl to insure the movement of the ore in the baskettoward the left 'hand end 'of the same, whereby the ore i-s directedtoward corresponding cups b y the pairs of inclined plates 19.

`Secured to each of the frame members39 is a bearing 59 for a shaft 60carrying a handle-bar 61 and an arm 62 pivoted toa link v'63 in turnmounted on the shaft 5:3, and

it will be seen that, if the bolts 58 be loosened, the rock-bars lmay beraised or lowered by means of the handle-bar 61 and held in a desiredposition until the bolts are again cording to the character of the ore,with the tailings on the top vof Vthe body of ore not entering saidcups, this being accomplished in vwater at a suitable depth, preferablyat aV water level six inches above the ore level; and that the inclined,adjustment of the elliptical path of the basket may be such as toaccommodate the jigfto ores Yof dfi-'Herent The purpose of the inclinedplates 19=is to draw the ore from the sides of the basket afterconcentration, and to enable us to secure different depths of bedding.This particular jig is designed to run witha two 'and 'one-half inchbedding of ore. If it becomes over .the jig in the correspondingcompartment, or, the gate is opened tocause a lighter 'bedding` in such"compartment," After the desired jig motion is adjusted, the cups mustbe adjusted to give the proper depth of bedding and grade of oredesired. To concentrate many different grades of ore as we do bychanging the motion of the jig, it is necessary to have this means forcontrolling the depth of the bedding, and the desired results lcoulfdnot be obtained by the motion alone, nor by the adjustment of the cupgates, as a complemental adjustment 'of the cup gates is essential to acertain adjustment of -the ypath of the jig, and the path of the jig ischanged to accommodate thel 'devi-ce to they diiferent grades andcharacters Jof ores.

We prefer to make the frame members 39 and the spring basket hangersslid-able along the length of the tank and the basket in order toaccommodate the jigto different sizes and weights of ores, anjd wereserve the right to Vmake such rother ohan'gesin vand modifications ofthe details of 'construction f bottom and having an opening-in the lowerpart of the front thereof, an adjustabie gate for controlling the-heightofthe upper edge of said opening, 'a partition in said cup arrangedtransverselv thereof andi provided with a-n opening intermediate ltheheight thereof, an adjustable gate for controlling the height of thelower edge of said partition opening, andldiagonally inclined overflowplates of greater height than said transverse plates leading from thewalls "of said screen to said-cup to directors to the `opening in thefront thereof.
